高尔夫球场草坪地下害虫蛴螬的研究

本研究以北京市昌平县国际高尔夫球场为试验基地 ,依不同的植被种类及管理水平 ,将该球场划分为 3个区 :草坪区 (球道和高草区 )、水域区和林灌区。对高尔夫球场这一特殊生态系统中蛴螬 (White grub)的种类、种群动态及空间生态分布进行了系统的调查和分析研究。据调查 ,共有 7个属、13个种 ,分别属于丽金龟科 (Rutelidae)和鳃角金龟甲科 (Melolonthidae) ;在草坪草全年的生长期中 ,蛴螬种群动态数量有 2个高峰期 :5月上旬至 6月上旬和 8月下旬至 9月中下旬 ;蛴螬种群数量变化的年际间无差异 ,高水平的草坪管理措施对蛴螬种群数量的增长具有一定的控制作用。春季是防治蛴螬的最佳时期 ,高草区、结缕草草坪、槐树林是防治的重点区域。

Study on underground pests (white grub) in turfgrass of golfcoures

For the special ecological conditions and management measures, there were different kinds and amount of pests with turf field. A study on the species type, population dynamics and spatial distribution of white grub was conducted in Beijing Changping International Golf Course from spring 1996 to spring 1997. There were 13 species, 7 genera of white grub, respectively belonging to Rutelidae and Melolonthidae. In growth season of turfgrass, population dynamics of white grub performed 2 active peak respectively from May to early June and from late August to late September. There was no difference between population number of different years. Excellent management played an important role in the control of white grub. Spring was time to control white grub and rough area, zoysias turf and Chinese scholar tree forest was the important area.
